Application filed Sept-ember 12, 1913. Serial No. 789,537.

1 0 all whom it may concern Be it known that I, GEORGE W. HOLLAND, acitizen of the United States, residing at Tombstone, in the county ofCochise and State of Arizona, have invented new and useful Improvementsin Pinch- Bars, of which the following is a specification.

The invention relates to an improvement in pinch bars, and particularlyto a bar of this type which may be readily and quickly handled for thepurpose in view and which will grip the rail head to prevent possibilityof rearward slipping during operation.

The main object of the present invention is the provision of a pinch barincluding an operating lever and a pressure foot slidably connected tosaid lever, the lever being provided with a gripping element mounted fora limited sliding play upon the pressure foot and provided beyond thesame with hooks to grip the head of the rail.

The invention in its preferred form of details will be described in thefollowing specification, reference being had particularly to theaccompanying drawings, in which Figure 1 is a perspective of theimproved pinch bar. Fig. 2 is a side elevation illustrating the use ofthe same.

Referring particularly to the accompanying drawings, the improved pinchbar comprises a pressure foot 1 having the forward end curved on theupper side in conformity with the curvature of the wheel and on thelower side to form a fulcrum 2 to bear upon the rail 3. The rear end ofthe pressure bar on its upper surface is formed with a concavity i toreceive the rounded or hooked end 5 of the operating lever 6, a tie loop7 being secured to the pressure foot and loosely overlying the hook endof the lever.

A holding member is connected to the hook end of the lever 8 comprisinga U- shaped frame 9 the upper terminals of the side bars of which arepivotally connected to the hook end of the lever, the lower cross bar 10being curved to cooperate with the tread portion of the rail and beingterminally provided with hooks 11 which engage beneath the tread portionof the rail. The pressure foot is provided with pins 12 which limit theplay of the locking member in one direction.

The application and operation of the improvement will be fully apparentfrom the above description and from Fig. 2 of the drawings, it beingnoted that the cooperation of the hooks with the head portion of therail serve to prevent backward movement of the pinch bar when reachingfor a new gr1p.

What is claimed is 1. A pinch bar including a pressure foot formed tocooperate with a wheel and with a rail, said foot being formed with aconcavity, an operating lever having a portion shaped to conform to theconcavity, a loop connecting said pressure foot and lever, and meanscarried by the lever to engage the head of the rail.

2. A pinch bar including a pressure foot formed to cooperate with awheel and with a rail, said foot being formed with a concavity, anoperating lever having a portion shaped to conform to the concavity, aloop connecting said pressure foot and lever, and a frame connected tothe lever and provided with means to engage the tread portion of therail.

3. A pinch bar including a pressure foot formed to cooperate with awheel and with a rail, said foot being formed with a concavity, anoperating lever having a portion shaped to conform to the concavity, aloop connecting aid pressure foot and lever, and a frame pivotallyconnected to the lever, and hooks carried by the frame to engage beneaththe head of the rail.

4. A pinch bar including a pressure foot formed to cooperate with awheel and with a rail, said foot being formed with a concavity, anoperating lever having a portion formed to conform to the concavity, aloop connecting said pressure foot and lever, a frame pivotallyconnected to the lever, hooks carried by the frame to engage beneath thehead of the rail, the cross bar of the frame bearing upon the treadportion of the rail to form a fulcrum for the operation of the device.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. HOLLAND.
